FIELD: genetic engineering, amino acids. SUBSTANCE: invention relates to a novel gene that encodes lysine decarboxylase and its nucleotide sequence is given in the description. Amino acid sequence of lysine decarboxylase is given in the description also. The strain E. coli showing a limited expression of said gene is cultured in the liquid nutrient medium and the end product is collected. EFFECT: new gene indicated above, increased rate of L-lysine producing. 3 cl, 3 dwg, 2 tbl, 3 ex
